Description
Technical Field
The invention relates to a luminescent plate for in vitro diagnosis, in particular to a method for measuring the volume of single-hole residual liquid of the luminescent plate.
Background
The luminescent plate comprises a 6-48-hole cell culture plate, a 96-hole enzyme label plate and the like, is a reaction plate used in an in vitro diagnosis and detection experiment, and is cleaned by a luminescent plate cleaning device, namely a plate washer after the experiment is finished.
After the luminescent plate is cleaned by using the plate washer, a certain amount of lotion still remains in the luminescent plate coating hole, and the volume of residual liquid remaining in the coating hole is used as an index for judging the performance of the plate washer in the industry. The plate washer is generally matched with an enzyme-labeling instrument/a luminescence instrument for use, and is widely used for cleaning luminescent plates in hospitals, blood stations, epidemic prevention stations, reagent manufacturers and research rooms. Compared with the final luminous reading, the plate washing link is an unobtrusive link in the experimental process, does not generate the final analysis result, and is easy to ignore by people. However, their performance is also closely related to the end result. Especially, in a 96-hole plate washing machine, the flatness of the washing head directly influences the volume of residual liquid, while the plate washing is generally carried out for 5-6 times, the residual liquid effect is accumulated, and the precision result of the whole plate experiment is directly influenced. Some plate washers fail to achieve a sufficiently low residual volume and also result in a high background or a large standard deviation. In order to ensure that the cleaning data of the light-emitting plate is accurate and reliable and provide more reliable data for medical inspection, the method has very important significance for measuring the volume of the residual liquid in a single hole of the light-emitting plate after the plate washer is washed.
Because the capacity of each hole of a 96-hole plate is very small, about 350-.
